Access/Release – Global Access/Release
Station/Repeater Control Mode Enable
Controls the Station/Repeater Enable Mode feature. If enabled, a mobile can enable the base station or
repeater remotely via a chosen prefix, followed by a **# command. This prefix, consisting of 1 to 6
digits, must be programmed in.
Station/Repeater Enable Prefix Code
Prefix to the **# Station/Repeater Enable command. It applies only if the Station/Repeater Enable mode
is active.
Mobile Inactivity Control
The maximum allowable pause in mobile activity during a conversation. Normally, this parameter
should be set to a maximum of 3 minutes. Consult applicable local rules before disabling. Its use
prevents the interconnect from tying up the phone and radio system if the mobile drives out of range or is
otherwise unable to drop the patch.
Overriding Access Time Limit by Mobile Command
When enabled, a mobile user can prevent the overall access time from expiring by using the ***
command.
Resets Access Timer to
Determines whether the *** command resets the access time to 1 minute or to the overall access time
limit.
Overall Access Time Limit
Valid range is 1 to 59 minutes of total access time before automatic disconnect occurs.
Time-Out Tick Duration
Determines the length of time prior to disconnect that time-out warning ticks are initiated. Valid range is
0–59 seconds. If set to 0, time-out ticks are disabled.
Control of External Devices via Security Code
When enabled, the monitor output will be activated upon reception of the security code. The monitor
relay must not be used for any other function, that is, it must not be wired to enable MONITOR. Not
applicable with VOX carrier detect method.
Security Code
Allows privileged users to enter a six-digit security code to override some unit functions. The valid
range for each digit is 0–9.
CTCSS Strip on Access
Determines whether the TX CTCSS disable output is automatically activated at the beginning of a
conversation. If enabled in a system that uses CTCSS, limited privacy is afforded to the mobile, as other
mobiles on hook will not hear the telephone conversation.
